Abstract

Process for closing orifices and/or protecting structures by reusing end-of-life tyres, which reduces environmental impact by not recycling through crushing, but rather through direct reuse. The tyre treads (1) are cut, separated from the flanks (2) and flatly disposed, for the ultimate purpose of disposing these on the orifice or surface to be protected. The treads (1) are mechanically joined by means of mechanical elements (3) and the structure created may be linear, two-dimensional or three-dimensional.

Description

Procedure for closing holes and / or protection of structures by reusing tires out of use.

Object of the invention

The present invention aims at provide a method for recycling by reuse of tires out of use, which reduces the environmental impact, without recycled by crushing, but by direct reuse. This is a procedure for closing holes and / or or structure protection, where the treads are cut of the tire, are separated from the flanks by arranging them in shape flat in one or several layers, continuous or discontinuous, to be placed on the hole or surface to be protected.

Background of the invention

Currently, the massive tire manufacturing and the difficulties to make them disappear once used is one of the environmental problems to which all countries owe face. Around the world there are hundreds of thousands of tons annual used tires and the production of new tires goes on the rise So far, for convenience and for lack of regulations clear about it, the main destination of the used tires was the landfill, controlled or uncontrolled.

Tire recycling consists of removing the steel and the fibers of the tire and then crush it. Pasta resulting is used for different purposes, as an improver of asphalt, noise and vibration attenuator, door stops, Bumpers, beacons, shoe soles, etc.

Direct reuse is the alternative environmental more efficient from all points of view, but It is very minority. So far, only one has been found tire reuse solution, of little importance and Very little relevance. For example, from the surveillance report Technology presented in February 2008 by the community of Madrid on the recovery of material and energy of tires outside of use, it follows that tire reuse focuses on the construction of artificial reefs, of tire bullets covered with concrete and temporary or solid floor tracks reinforced based on superimposed layers of whole tires filled with compacted granular material.

With regard to patents, ES 2151886 stands out, which deals with a building material, blocks of material and manufacturing procedure, used to build roads, parking areas and streets, and preformed blocks for buildings and the like Said material comprises 25 to 55% by volume of asphalt, from 10 to 40% by volume of polyethylene, from 5 to 35% in volume of monofilament fiber material and 5 to 35% by volume of elastomeric material. Also the patent ES 2222504 describes a soil structure, which includes a subsoil of a surface area determined, a bottom layer of a sound absorbing substrate made of a resilient material, and a top floor placed on top and glued to the bottom layer, where the cavities provided on the bottom surface of the substrate consist of U or V shaped cross-section grooves that are parallel to each other and extend at an angle to the lateral edges of the substrate; and the resilient material is manufactured of recycled rubber. Patent ES 2257928 deals with a plate of sound insulation where the absorbent material is manufactured with crushed rubber from recycled tires mixed with a binder commercially called EVA or POLYURETHANE, in a proportion that in the preferred embodiment has 80% material base and 20% binder.

The three previous patents deal with the formation of different structures for the manufacture of roads, floors, buildings, and even as acoustic insulation, also containing the process for obtaining it, mixing with unused tires in different proportions and others elastomers In the present invention, the recycling of said tires are achieved directly, so that it is not recycled the tire undergoing pre-use treatment, but that its use is direct, separating it directly from the flank of the tire. In addition, the invention under study is used said tire for various applications where it had not been previously used The way to join different layers of material is done mechanically with through elements, thus avoiding various glues.

The present invention differs from the state of technique both in the form of the modular system and in the procedure for placing it, and in the applications to which It is destined.

Unlike the current tendency to recycle By grinding the tire, this invention is based on the Recycled through reuse, energy process more Efficient, cheaper and simpler.

Another big difference is the non-use of reinforcements as an internal stiffener element if the modular barrier system to reduce impacts, as obtains a product whose armor is the original of the tire. In addition, the union of the bands with each other does not resort to glue, but it is done mechanically.

Description of the invention

The present invention relates to a procedure to close gaps or protect surfaces natural or artificial structural, through a modular system which can have a predominant dimension (forming a tape), two (forming a sheet), or none (forming a solid three-dimensional). The union of this modular system to another structure It can be on time or continuously.

In this way, the object of the invention is double, because in addition to allowing the enclosure or protection, allows the reuse of used tires, reducing the impact environmental.

The modular system is formed by joining Mechanics of tire treads out of use, a once cut, separated from the flanks and arranged flat. The bands to join can have the same dimensions or not, being able to dispose of continuously or discontinuously, leaving gaps or not between adjacent bands.

The joining of treads to each other is made using through elements, which can be screws, roblones, staples, cables, wires, tapes or similar elements of plastic, metal, fabric or any other material resistant. The thickness of the modular system depends on the use to which it is destine, being able to have a single layer or several.

The modular system can be treated superficially to avoid damage by ultraviolet rays, attacks chemicals or other agents that affect rubber or armor the tires. In the same way, it can be treated for purposes aesthetics: painted, labeled, etc.

The surfaces or volumes obtained can be intended for the closing of gaps of natural structures or artificial or to avoid all kinds of mechanical aggressions surface (impact, abrasion, erosion, cavitation, etc.).

The modular system may or may not adhere to the external structure; in the case of wanting to unite it, the type of union It depends on the structure. The whole structure or only the points of contact with the modular system can be protected by placing tire flanks, which is of particular interest when impacts are anticipated, as in the case of roadside barriers.

Preferred Embodiment of the Invention

The present invention relates to a procedure for the closing of holes and / or protection of structures by reusing out-of-use tires that It comprises the following stages:

(to)

cut the treads (1) of the tires out of use,

(b)

separate from the flanks (2), arranging them flat,

(C)

form a solid by combination of bands (1) of different tires, creating a structure according to needs,

(d)

place over the hole or surface to to protect.

The structure created is formed by the mechanical attachment of the tread bands (1) of out-of-use tires. The bands to be joined can have the same dimensions or not, being able to be arranged continuously, leaving gaps or not between bands
adjoining

The mechanical connection of the treads is performs by means of through elements (3), such as screws, roblones, staples, cables, wires or similar elements of plastic, metal, fabric or any other resistant material. He Modular system thickness depends on the intended use, of so that a single layer can be created, where the union between edges contiguous can be with overlap or with lips, or several layers. So same, by combining said treads (1), we will obtain a linear, superficial or three-dimensional structure of also according to the needs.

The modular system can be treated superficially to avoid damage by ultraviolet rays, attacks chemicals or other agents that affect rubber or armor the tires. In the same way it can be treated for purposes aesthetics, such as painted, labeled, etc.

The modular system may or may not adhere to the external structure, being able to be simply superimposed. In if you want to join it firmly, the type to the structure It depends on it. For example, if there are posts, you can take advantage by passing the tape or sheet around them or embrace them by closing a loop using a connecting element, such as clamps, anchoring anchors, etc., or simply drilling the structure and solidarity both with a passing element.

The whole structure or only the Contact points with the modular system can be protected by placing flanks (2) of tires, ensuring this way the damping of possible impacts at this point Contact. This protection can be integral, lining the structure, or only one way. This is particularly useful. when high energy impacts are expected, as in the case of roadside barriers.

In Figures 3 to 10, you can see different configurations adopted by the treads for different applications The proposed system allows for example stop pure abrasion or friction wear on bridge piles, spillways and canals, pipes, forest tracks and others structures that require it. It also attenuates erosion abrasion or impact, continued or punctual, on port dikes, barriers of containment, road safety barriers, etc. In addition, abrasion by cavitation that this palia system is the one produced on spillways and channels or other surface where necessary.

Another important application of the system would be as an anti-pollution sheet when depositing on the ground preparations of aggregates or other substances that can contaminate it.

The application as lined allows to isolate acoustically or thermally the structure it protects, such as industrial buildings, air chambers in homes, covered with unique buildings, ships, etc.

If the bands overlap properly, you can use the modular surface as a cover, well supported on a solid that you want to protect (aggregates, structures, etc.), well self-supporting on supports at its ends or supported on cables or beams It can also be used for waterproofing the structure, as in the case of landfills, screens of dams of loose materials, concrete subjected to frost processes or chemical actions, etc.

Being able to form a three-dimensional solid, its industrial application can be the construction of protections against waves, embankment support, etc.

In the particular case of being placed in order to cushion impacts, tire treads they get the dissipation of that kinetic energy, part by deformation and part by transmission to the structure to which it is united. In particular, the modular system can be placed forming a continuous belt under the metal road barrier in order to retain motorcyclists and cyclists in their trajectory that may suffer an accident, as well as lessen the impacts that They suffer with the metal structure.

In addition, since its surface has a very low elastic modulus, it can also be used to protect from impacts of low energy and where it should be reduced the damage on the body that impacts, as in playgrounds, access to garages, etc.
